Kempower builds one of Austria's largest e-depot in Vorarlberg, scalable to 84 chargers - Sustainable Bus

"A high-capacity electric bus charging hub built with Kempower systems has entered operation in Wolfurt, supporting the electrification of public transport services operated under the KVG Vorarlberg network. The project has been developed by vlotte vkw, a subsidiary of regional utility VKW, in cooperation with Verkehrsverbund Vorarlberg (VVV), with Österreichische Postbus AG operating the buses. Up to 125 battery-electric buses have entered service in Vorarlberg since the end of 2025."

"The depot, located at the Wolfurt freight station, includes 54 charging points in its initial phase, each delivering up to 240 kW. The site is designed for expansion to 84 charging points. Power supply is ensured by a total transformer capacity of 5 MW, distributed across four 1.25 MW transformers. Charging infrastructure is based on Kempower's distributed architecture, separating power units from charging satellites."

"The system supports both high-power charging during short operational stops and lower-power overnight charging. Intelligent charge management via Kempower's ChargeEye software aligns charging profiles with bus schedules, aiming to maximize vehicle availability and operational reliability. In addition to traction charging, the infrastructure enables battery and interior preconditioning, improving range consistency, energy efficiency, and passenger comfort. The initial 200 kW power unit is scalable to 400 kW, allowing flexible power allocation across multiple vehicles, Kempower points out in a press note."

The Wolfurt depot in Vorarlberg is a high-capacity electric bus charging hub built with Kempower distributed charging technology. The site initially includes 54 charging points delivering up to 240 kW each and can expand to 84 points, supported by a 5 MW transformer capacity split across four 1.25 MW units. The Kempower architecture separates power units from charging satellites and features a scalable 200 kW power unit upgradable to 400 kW. Intelligent charge management via ChargeEye aligns charging with timetables for high-power short stops and overnight low-power charging. The infrastructure also enables battery and interior preconditioning to improve range consistency, energy efficiency, and passenger comfort, supporting deployment of dozens of electric buses and further fleet growth.
